 *                 This represents the maximum size of a datagram payload
 *                 handled by the transport layer (usually UDP) as determined
 *                 by the network link and stack. In practice, this controls

 *
 * \note           The limit on datagram size is converted to a limit on
 *                 record payload by subtracting the current overhead of
 *                 encapsulation and encryption/authentication if any.
 *
 * \note           This can be called at any point during the connection, for

 *
 * \note           This setting only controls the size of the packets we send,

 *
 * \note           If both a MTU and a maximum fragment length have been

 *                 lower limit on record payload (see first note) is used.
 *
 * \note           This can only be used to decrease the maximum size
 *                 of datagrams (hence records, see first note) sent. It

 *
 * \note           When this function returns #MBEDTLS_ERR_SSL_WANT_WRITE/READ,
 *                 it must be called later with the *same* arguments,
 *                 until it returns a value greater that or equal to 0. When
 *                 the function returns #MBEDTLS_ERR_SSL_WANT_WRITE there may be
 *                 some partial data in the output buffer, however this is not
 *                 yet sent.

 * \note           If the requested length is greater than the maximum
 *                 fragment length (either the built-in limit or the one set
 *                 or negotiated with the peer), then:
 *                 - with TLS, less bytes than requested are written.
 *                 - with DTLS, MBEDTLS_ERR_SSL_BAD_INPUT_DATA is returned.
 *                 \c mbedtls_ssl_get_max_frag_len() may be used to query the
 *                 active maximum fragment length.
 *
 * \note           Attempting to write 0 bytes will result in an empty TLS
 *                 application record being sent.

 * \brief           Callback type: start fal signature operation.
 *
 *                  This callback is called during an SSL handshake to start
 *                  a signature decryption operation using an
 *                  external processor. The parameter \p cert contains
 *                  the public key; it is up to the callback function to
 *                  determine how to access the associated private key.
 *
 *                  This function typically sends or enqueues a request, and
 *                  does not wait for the operation to complete. This allows
 *                  the handshake step to be non-blocking.
 *
 *                  The parameters \p ssl and \p cert are guaranteed to remain
 *                  valid throughout the handshake. On the other hand, this
 *                  function must save the contents of \p hash if the value
 *                  is needed for later processing, because the \p hash buffer
 *                  is no longer valid after this function returns.
 *
 *                  This function may call mbedtls_ssl_set_async_operation_data()
 *                  to store an operation context for later retrieval
 *                  by the resume or cancel callback.
 *
 * \note            For RSA signatures, this function must produce output
 *                  that is consistent with PKCS#1 v1.5 in the same way as
 *                  mbedtls_rsa_pkcs1_sign(). Before the private key operation,
 *                  apply the padding steps described in RFC 8017, section 9.2
 *                  "EMSA-PKCS1-v1_5" as follows.
 *                  - If \p md_alg is #MBEDTLS_MD_NONE, apply the PKCS#1 v1.5
 *                    encoding, treating \p hash as the DigestInfo to be
 *                    padded. In other words, apply EMSA-PKCS1-v1_5 starting
 *                    from step 3, with `T = hash` and `tLen = hash_len`.
 *                  - If `md_alg != MBEDTLS_MD_NONE`, apply the PKCS#1 v1.5
 *                    encoding, treating \p hash as the hash to be encoded and
 *                    padded. In other words, apply EMSA-PKCS1-v1_5 starting
 *                    from step 2, with `digestAlgorithm` obtained by calling
 *                    mbedtls_oid_get_oid_by_md() on \p md_alg.
 *
 * \note            For ECDSA signatures, the output format is the DER encoding
 *                  `Ecdsa-Sig-Value` defined in
 *                  [RFC 4492 section 5.4](https://tools.ietf.org/html/rfc4492#section-5.4).

 *                        is registered with mbedtls_ssl_conf_sni(), then

 * \brief           Callback type: generate and write session ticket
 *
 * \note            This describes what a callback implementation should do.
 *                  This callback should generate an encrypted and
 *                  authenticated ticket for the session and write it to the
 *                  output buffer. Here, ticket means the opaque ticket part
 *                  of the NewSessionTicket structure of RFC 5077.
 *
 * \param p_ticket  Context for the callback
 * \param session   SSL session to be written in the ticket
 * \param start     Start of the output buffer
 * \param end       End of the output buffer
 * \param tlen      On exit, holds the length written
 * \param lifetime  On exit, holds the lifetime of the ticket in seconds
 *
 * \return          0 if successful, or
 *                  a specific MBEDTLS_ERR_XXX code.
